Abstract (en)
[origin: WO2021111258A1] A plant for building tyres for vehicle wheels comprises a gripping ring (400) arranged in a fixed reference position. A first stage building line (200) defines a closed first-stage path (201) for the movement of a plurality of building drums (202) and an open first-stage path (203) for building and moving carcass sleeves being processed (204). A second stage building line (300) defines a closed second-stage path (301) for the movement of a plurality of auxiliary drums (302) and an open second-stage path (303) for building and moving a plurality of outer sleeves being processed (304). The open second-stage path (303) and the open first-stage path (203) terminate at the gripping ring (400) configured for carrying out radially outer contrast function during the shaping of a first carcass sleeve being processed (204a) and the assembly thereof with a first outer sleeve being processed (304a).
